Credit HF - Final Round Interview - What to expect

As the title says, after 4 rounds I got to the final in-office round at a credit HF (corporate + event driven).

Relatively small size (below 500mm-1bn), and in the previous rounds I completed a case study.

This is my first final round in the HF space and I was wondering what I should expect: paper modelling test+cooked on technicals or it's just an informal chat to see if I fit in the culture?

Thanks.
